METALLIC SPRING-MATTRESS.

Specification of Letters Patent.

Patented June 24, 1919.

Application filed March 18, 1918. Serial No. 223,109.

To all whom it'may concern Be it known that I, J OSEPH EISTEIN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Metallic Spring-Mattresses, of which the following is a specification.

The invention pertains to metallic spring fabrics for use on beds, and it consists in the novel features and structure hereinafter described, and particularly pointed out in the claims. The spring of my invention comprises a main carrying frame and'a fabrlc composed of interengaged links of special outline connected by coiled springs with the end bars of said frame and at their side edges with fiat bars which extend above the side bars of the aforesaid frame and are connected at their ends by coiled springs with the aforesaid end bars, the structure as a whole being complete in itself and adapted to be handled as a unit and applied to or removed from the customary bedstead. One of the essential objects of my invention is to provide a fabric whose links may be readily assembled and which will have a special yielding action due to their particular shape. Each link has parallel sides for a definite length and thence converging sides terminating at their point of approximate juncture with an eye into which an adjacent link may be hooked. At the ends of the parallel sides of the links are formed hooks to engage the eyes of adjacent links in series.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Figure 1 is a top view, partly broken away, of a spring constructed in accordance with and embodying the. invention;

Fig. 2 is a top view on a larger scale of one corner portion of the same;

Fig. 3 is a horizontal section-through a portion of the same, taken about on the dotted line 33 of Fig. 2;

Fig. l is a detached perspective view of one of the links employed generally throughout the spring, and

Fig. 5 is a perspective view of a special shape of link which I employ at opposite side edges of the spring for connecting the fabric with the side or edge bars therefor.

In the drawings, the main rigid frame for supporting the spring fabric is numbered 10 and comprises side bars 11 and angle end bars 12, which bars 12 have upturned members 13 to which the spring fabric is, by means of coiled springs 14, tautly connected.

The fabric is composed of the main individual links 15 (Fig. 4) and edge links 16 of modified construction and one of which is shown in Fig. 5. The links 15 correspond in construction with one another and one of said links is shown in Fig. 4, and each of the links 15 has parallel side members 17 and converging side members 18, and at the point of juncture between the members 17 18 the link is bent at an angle, as shown at 19. The converging side members 18 terminate in an eye 20 which is on the longitudinal center line of the link and constitutes one end thereof. The side members 17 are formed with hooks :21, 22, respectively, which represent the opposite end of the link or the end opposite to the eye 20. The special construction of the sides of the links 15, these sides having the angles 19, parallel members 17 and converging members 18, constitutes an important feature of my invention, said sides having been given the special construction shown and described so as to obtain a yielding action at the angles 19 when the fabric is in use.

The first row of links 15, starting from the head end of the main frame, are connected with the adjacent springs 141 by means of small plates 23 which have endeyes '24 to receive hooked ends of the said springs 11 and eyes 25 into which adjacent hooks 21, 22 of the links 15 are caught, as shown at the upper portion of Fig. 2. The links 15 are arranged in parallel transverse rows and the members 17 of adjacent links come together in the assembled fabric. The links 15 in the first or top row, looking at Fig. 2, receive in their eyes 20 the hook-ends 21, 22 of the links 15 in the next adjacent row of links, and this method of assembling is carried out throughout the fabric and whereby the eyes of one row of links 15 are in line with the side members 17 of adjacent links in the next adjacent row. The row of links at the other end of the main frame 10 or at the lower end, looking at Fig. 1, have their eyes 20 caught upon the hooked inner ends of the adjacent springs 14, the plates 23 in this in stance not being required for connecting the fabric to the said springs 14, shown at the lower end of Fig. 1.

The side or edge links 16 have a side member 26 to'li'e againsta member" 17 of the'next bers 18 of the links 15, an eye 28 to receive the hook-end of one of the side members 17 of the adjacent link in the next transverse row of links, as shown at the left hand portion of Fig. 2, and an arm 29 having on its end a hook 30 to entera hole 31 in the longitudinal flat bar which extends longitudinally of the main frame 10. Links 16 will be provided at each edge of the spring fabric, and these links will engage the bars, 32, which are above the sides'll of the main frame 10 and are connected at their ends by springs 33 with the end members 12 of said main frame 10.

I employ the links 1 6, which represent about one longitudinal half of a link 15, so as to permit me to fill out the fabric as nearly as possible to the side bars 32 and to render it convenient to connect the side edges of the fabric with the aforesaid bars The links 16 are angular, as at 34:, at the juncture between their side members 26, 27, and in this regard the links 16 match the adjacent sides of the adjacent links 15. The links 16 have at the outer ends of their side members the hooks 35, and these hooks 35 at one end of the fabric are engaged within the eyes 25 of the plates 23, as shown in Fig. 2, and at all other portions of the fabric the hooks 35 of said links 16 engage eyes 20 of links 15. The side members 26, 27 of the links 16 are substantially co-equal in length, and the side members 17, 18 of the links 15 are substantially co-equal in length and also substantially co-equal in length respectively with the side members 26, 27 of the links 16.

My invention as a whole has been desi ned with a view of producing a highly efficient, desirable, durable and easily constructed spring for a bedstead, and my invention resides in the special formation of the links 15 I have designed and also in the special construction of the links 16 for cooperation with the links 15 and with the downwardly yieldable fiat sheet metal bars 32 to which said links 16 are connected and which links,

16 serve to connect the side edges of the fabric as a whole with said bars 32. The bars 32 are flexible so as to yield downwardly, and they also may yield with the fabric of the spring as a whole, since said bars are connected at their ends with the coiled springs 33.

What I claim as my invention and desire to secure by Letters-Patent, is:

'1. A bed-spring of the character described comprising a rigid carrying frame, coiled springs connected. with the end members Copies of this patent maybe obtained for five cents each, by addressing having hooked side members thereof, yieldable side-bars above the sides of said frame and connected by the outer of said coiledsprings with the end members of said frame, and a fabric connected with the inner ends of the other of said coiled springs, said fabric comprising links connecting the same at its side edges with the said bars and links. in a series of transverse rows, the links of each row having parallel side members, converging side members ex tending therefrom, eyes at the juncture of the converging side members and hooks at the outer ends of the parallel side members, with the hooks of adjacent matching parallel side members of adjacent links engaged with the eyes of the links in the next adj oining row of links, and the links connecting the edges of said fabric with said side bars to engage the eyes in the adjacent side links of said rows of links, eyes to receive the hooked ends of side members of said rows of links and arms having hooked ends to engage holes in said side bars.
